Latest Patents

Logothetis holds a patent for a "Kalman filter based equalization for digital multicarrier communications systems." This computer-implemented approach focuses on reducing distortion in digital communications systems. The method involves obtaining an optimal estimation of the original data using a Kalman filter with an increased length state to effectively remove inter-symbol interference (ISI) in the time domain. The implementation of an increased length state in the Kalman filter allows for a more accurate estimate of the transmitted data with minimal additional computational cost. Furthermore, subsequent equalization can be performed in the frequency domain to correct any remaining amplitude and phase distortion.
